jhibbits a551224a60 Create crtsavres.o for powerpc builds
Summary:
GCC expects to link in a crtsavres.o on powerpc platforms.  On
powerpc64 this is an empty file, but on powerpc and powerpcspe this does contain
some save/restore functions, which may not actually be necessary for newer
modern GCC and clang.  This appeases the in-tree gcc, though, and is needed in
order to switch to the BSD CRTRBEGIN.
